EC-COUNCIL EC-Council Digital Forensics Essentials (DFE) Sample Questions (Q15-Q20):

NEW QUESTION # 15
Which of the following data acquisition formats supports the Lempel-Ziv-Markov chain (LZMA) algorithm for compression?

Answer: A

Explanation:
In digital forensics, acquisition formats differ mainly in how they store evidence data, metadata, and whether they support features like compression, segmentation, and integrity verification. ARaw formatis a sector-by- sector bitstream image (often called "dd" style) and typically doesnotdefine built-in compression or structured metadata; any compression would be external to the format. "Proprietary format" is not a single defined standard-some proprietary images may compress data, but the option is too generic and not tied to a specific, documented compression method.
The format known in forensic documentation for explicitly supporting modern compression such asLZMAisAFF4 (Advanced Forensic Format 4), which is designed as a next-generation container supporting rich metadata, hashing, chunked storage, and pluggable compression options. AFF4's architecture stores evidence in compressed chunks/streams and commonly associates LZMA with efficient, high-ratio compression while preserving forensic requirements such as repeatable verification through cryptographic hashes.
The option "Advanced ForensicFramework 4" corresponds toAFF4in many exam question banks and training materials. Therefore, the correct choice isC, because AFF4 is the acquisition format recognized for supportingLZMA compressionas part of its standardized capabilities.


NEW QUESTION # 16
In which of the following attacks does an attacker trick high-profile executives such as CEOs, CFOs, politicians, and celebrities to reveal critical corporate and personal information through email or website spoofing?

Answer: A

Explanation:
The scenario describes a targeted social-engineering attack aimed specifically athigh-profile individuals (CEOs, CFOs, politicians, celebrities) and usesemail or website spoofingto deceive them into disclosing sensitive information. In digital forensics and incident response documentation, this is most accurately categorized aswhaling, a specialized form of phishing that focuses on "big targets" (often called "high-value targets" or "VIPs"). Whaling campaigns typically use highly tailored pretexts (e.g., legal subpoenas, board communications, invoice/payment requests, HR or executive directives) and may include spoofed sender domains, look-alike websites, or fraudulent login pages to harvest credentials and confidential corporate data.
Because executives often have access to financial systems, strategic documents, and privileged communications, attackers concentrate effort on realism and personalization, making whaling distinct from broad, generic phishing.
By contrast,smishingis phishing conducted via SMS/text messages,spimmingis spam over instant messaging platforms, andidentity fraudis a broader category involving impersonation/misuse of personal data but does not specifically denote the executive-targeted spoofing technique described. Therefore, the attack type in the question isWhaling (A).


NEW QUESTION # 17
John, a forensic officer, was working on a criminal case. He employed imaging software to create a copy of data from the suspect device on a storage medium for further investigation. For developing an image of the original data, John used a software application that does not allow an unauthorized user to alter the image content on storage media, thereby retaining an unaltered image copy.
Identify the data acquisition step performed by John in the above scenario.

Answer: C

Explanation:
The scenario emphasizes that John used an application (or mechanism) thatprevents alteration of the acquired image content, ensuring the image remainsunalteredand protected from unauthorized modification. In forensic acquisition standards, this corresponds toenabling write protectionduring imaging-commonly implemented using awrite blocker(hardware or controlled software write-protection) to prevent any writes to the source evidence and, where applicable, to protect the integrity of the evidence copy from accidental or unauthorized changes. The purpose is to preserve evidential integrity by ensuring that neither the original media nor the forensic image is modified during handling, analysis preparation, or transfer.
"Validated data acquisition" refers to confirming the image is an exact duplicate, typically by computing and comparing cryptographic hashes (e.g., MD5/SHA) of the source and the acquired image. While validation is essential, the question specifically highlightspreventing alteration, not verifying equality. "Sanitized the target media" is the step of wiping/clearing the destination drive before acquisition to avoid contamination, which is not what is described. "Planned for contingency" relates to operational planning for unexpected issues (equipment failure, encryption, power loss), not integrity protection. Therefore, the best match isEnabled write protection on the evidence media (A).


NEW QUESTION # 18
David, a cybercriminal, targeted a community and initiated anti-social campaigns online. In this process, he used a layer of the web that allowed him to maintain anonymity during the campaign.
Which of the following layers of the web allowed David to hide his presence during the anti-social campaign?

Answer: C

Explanation:
The layer of the web most associated withmaintaining anonymityfor users and services is theDark Web. In digital forensics terminology, the Dark Web refers to services hosted on overlay networks (such as Tor hidden services) that arenot indexed by standard search enginesand are typically accessible only through specialized software and configurations. Its core characteristic is that it is deliberately designed to reduce traceability by routing traffic through multiple relays and separating identifying information (like the user's real IP address) from the destination. This makes attribution and geolocation significantly harder using traditional network logs alone, which is why adversaries often choose it to conduct covert communications, host content, or coordinate campaigns.
By contrast, theSurface Web(the regular, indexed portion of the web) is generally reachable through normal browsers and is easier to monitor and attribute using conventional ISP, server, and platform logs. "World Wide Web" is a general term for web content accessed via HTTP/HTTPS and does not specifically imply anonymity. TheDeep Webrefers to content not indexed by search engines (e.g., webmail, databases, authenticated portals), but it is not inherently anonymizing-many deep web resources are simply private or access-controlled. Therefore, the layer enabling David to hide his presence is theDark Web (C).


NEW QUESTION # 19
Jack, a forensic investigator, was appointed to investigate a Windows-based security incident. In this process, he employed an Autopsy tool to recover the deleted files from unallocated space, which helps in gathering potential evidence.
Which of the following functions of Autopsy helped Jack recover the deleted files?

Answer: C

Explanation:
When a file is deleted on common file systems, the operating system typically removes the directory reference and marks the previously used clusters/blocks asunallocated, but the underlying file content may remain on disk until it is overwritten. Digital forensics procedures emphasize that recovering such deleted content often requires examining unallocated space rather than relying only on file system metadata.Autopsy's "Data Carving"function is specifically intended for this purpose: it scans unallocated space (and sometimes slack space) forfile signatures(headers/footers and internal structure patterns) and reconstructs recoverable files even when the original filename, path, or metadata is missing.
This directly matches the scenario: Jack recovered deleted files fromunallocated space, which is the classic use case for carving. The other options in Autopsy support different investigative goals.Timeline analysiscorrelates timestamps from multiple artifacts to reconstruct sequences of activity, but it does not itself reconstruct deleted file content from raw disk areas.Web artifactsfocuses on browser history, downloads, cookies, and related traces.Multimediahelps categorize and analyze media files (e.g., images/videos), but it is not the primary mechanism for recovering deleted data from unallocated space. Therefore, the Autopsy function that enabled the recovery described isData carving (D)
